The oldest model that IBM still supports is the z13. Considering that each generation can "emulate" the previous two generations in hardware (via the "IBC" feature of the CPUs), this means that everything that is older than z114/196 is not an officially supported CPU model anymore. The Linux kernel still support the z10, so if we also take this into account, everything older than that can definitely be considered as a legacy CPU model. For downstream builds of QEMU, we would like to be able to disable these legacy CPUs in the build. Thus add a CONFIG switch that can be used to disable them (and old machine types that use them by default).
